Abstract People of all ages, cultures and backgrounds gesture when they speak. These hand movements are so natural and pervasive that researchers across many fields – from linguistics to psychology to neuroscience – have claimed that the two modalities form an integrated system of meaning during language production and comprehension. This special relationship has implications for a variety of research and applied domains. Gestures may provide unique insights into language and cognitive development, and also help clinicians identify, understand and even treat developmental disorders in childhood. In addition, research in education suggests that teachers can use gesture to become even more effective in several fundamental aspects of their profession, including communication, assessment of student knowledge, and the ability to instill a profound understanding of abstract concepts in traditionally difficult domains such as language and mathematics. This work converging from multiple perspectives will push researchers and practitioners alike to view hand gestures in a new and constructive way.
